So, my transfer finally finished after ~28 hours. I decided to not copy my Arq back-up's as that was another 5TB. I did a re-run of the command I used before to be sure nothing was missed but it looks like it already downloaded everything. (no .cloud files anymore).
I'm now copying to G-Drive with the following command, I'm starting with the folder called
Films so I can see if everything goes smoothly before I transfer the other stuff:
rclone copy ~/odrive-agent-mount/Amazon\ Cloud\ Drive/Media/Films/ gdrive:Media/Films
I've used a custom client_id and client_secret because I would need it later for plexdrive anyway.
Speeds are very nice Avg: 1.27 GBit/s. Should be done tomorrow evening I hope (got some tv show catching up to do than!) After that, it's time to request a refund from Amazon..
